Stress Testing

Stress Testing at Palm Beach Cardiology Center

Cardiac stress test is a test used to measure the heart’s ability to respond to external stress in a controlled clinical environment. They are most commonly used for assessment of the heart’s own circulation (the coronary arteries) to meet the demands of the stress induced by exercise. The stress test can be performed with or without imaging for further assessment. An echocardiogram or a nuclear dye/camera can be used to assess the heart’s blood flow demands in greater detail. For patients unable to exercise on a treadmill, we use a brief acting chemical agent to mimic the heart’s response to stress.

Stress Testing Q & A

What is a stress test?

A stress test, also known as an exercise stress test or cardiac stress test, is a diagnostic procedure used to evaluate how well the heart functions during physical activity. It helps assess the heart’s response to exercise and can identify issues such as coronary artery disease, exercise-induced arrhythmias, and overall heart function.

Why would I need a stress test?

A stress test is often recommended if you experience symptoms such as chest pain, shortness of breath, or dizziness during physical activity. It is also used to evaluate heart function before and after a cardiac procedure or surgery, assess the effectiveness of treatment, and determine your risk of heart disease.

How is a stress test performed?

During a standard exercise stress test, you will walk or jog on a treadmill or use a stationary bike while your heart rate, blood pressure, and ECG (electrocardiogram) are monitored. The exercise intensity gradually increases to assess how your heart performs under stress. If you are unable to exercise, a pharmacological stress test may be performed using medication to simulate the effects of exercise on the heart.

Are there any risks associated with a stress test?

While stress tests are generally safe, they can carry some risks, especially for individuals with existing heart conditions. Potential risks include abnormal heart rhythms, chest pain, or, in rare cases, a heart attack. Your healthcare provider will evaluate your health status to determine if a stress test is appropriate for you.
